General Description

The Telex Legacyä Series is a full duplex

(simultaneous talk and listen), multi-channel, wireless

intercom system. Legacy offers a complete solution

for 2 to 7 (or more) coaches per sideline, fast and easy

set-up, durable beltpacks, 64 bit audio encryption, and

professional grade headsets.

The main components of the Legacyä series consists

of the XO-1 beltpack and the XO-AP base station.

The XO-1 beltpack offers the user two separate audio

channels and the ability to communicate on both

channels at the same time. The user can talk and listen

on these channels or just turn off the talk button and

listen only. The beltpack uses an internal rechargeable

Li-Ion battery that will provide up to 8 hours of

uninterrupted operation.

The XO-AP base station can support up to 10 XO-1

beltpacks when the RF spectrum is clear. The base

station provides a central relay location which handles

the audio traffic between beltpacks. The built-in base

station intelligence called ClearScan™ automatically

selects the best RF (Radio Frequency) channel for

communications on start-up. The base station also uses

an internal rechargeable Li-Ion battery that will

provide up to 10 hours of uninterrupted operation.

System Features

• Easy base station and beltpack setup.

• Uses mature 2.4GHz IEEE 802.11 Wireless LAN

Technology.

• Audio in the system is encrypted via a 64 bit DES

algorithm.

• Base station automatically selects the clearest RF

channel for the system, and sets the system on that

channel. No user intervention is needed.

• Easy to read base station LED display to indicate the

RF channel of the system.

• If desired, the user can select any one of the eleven

standard 802.11 channels for the system to operate

via a single button on the XO-AP front panel.

• Durable, water resistant, ABS, beltpack cases.

• Dependable, rechargeable, wide temperature range,

Li-Ion batteries.

Set-up

Prior to use, the XO-1 beltpacks and the XO-AP base

station need to have their battery packs fully charged.

Refer to the charging instructions of this section.

1. Place the XO-AP base station in the area of use.

2. Attached the two antenna cables from the antenna

to the XO-AP. The cable marked, “Receive”

connects to the receive jack on the XO-AP. The

cable marked, “Transmit” connects to the transmit

jack on the XO-AP. The front label of the XO-AP

indicates the RF (Radio Frequency) connector

designation.

Aim the directional panel antenna at the area of

beltpack use. For example, in Figure 5-2, the

XO-AP is used in a football application where the

XO-AP is located in the press box and the antenna

is pointed toward the near side coach’s box.

NOTE: Make sure the antenna’s path to the area of

coverage has clear line-of-sight.

4. Plug the XO-AP’s external power supply into an

AC outlet if available. If external power is not

available then the XO-AP can run off internal

battery (if already charged).

System Operation

1. Turn on the XO-AP by pressing the power switch

into the On position. The XO-AP must be

powered-up before any beltpacks are turned on.

The following turn on events should follow:

• The power light on the front panel will activate

immediately.

• After 20 seconds the;

° AP active light will turn on solid.

° Channel indicator will illuminate all

segments of the display.

° The power light will turn red then back to

green.

• The XO-AP will then initiate a clear scan of the

11 RF channels of the 2.4 GHz spectrum (will

take about 4 seconds).

• The XO-AP will finally place the unit on the

clearest RF channel and indicate it has finished

booting by flashing the AP active light.

2. You can now scan for another channel, manually

select a channel or lock the current channel by

using one of the following procedures:

• Clear Scan – Hold the <SELECT> button until

the decimal point starts to blink (about 3

seconds) then release. The XO-AP will scan all

available channels and then set itself to the

clearest channel available for use.

• Manual Set – Press the button <SELECT> to

the XO-AP channel desired. Each press of the

button will increment the channel by one. Once

the desired channel is displayed the XO-AP will

automatically set to that channel.

• Lock – Press and hold the <SELECT> button

until the decimal point is on solid (about 10

seconds) then release. The XO-AP is now

locked on that RF channel. The only two ways

to unlock it are to reboot the XO-AP or hold the

<SELECT> button down again until the

decimal point turns from solid to off (about 10

seconds).

3. With the XO-AP running, turn on the XO-1

beltpacks one at a time. The following turn on

events should follow:

• The battery light will activate immediately.

• After 20 seconds;

° A voice in the headphone will say, “wireless”

indicating the beltpack is in wireless mode

(as opposed to “wired” mode used for

changing the encryption code, see section 6).

° The “O” light will lite and communications

will start.

4. Wear the beltpack on the hip. Place them in a

position that allows for greatest visibility to the

XO-AP antenna in the press box.

5. XO-1 Top Panel Buttons – The XO-1 has three top

panel buttons:

• TALK – This button enables/disables the

beltpack’s microphone.

Enabled - The audio channel light(s) are on

solid and sidetone (your own voice heard in

your headphones) can be heard.

Disabled – The audio channel light(s) blink and

there is no sidetone.

Talk has two modes of operation:

° Latch – Tap the button to enable the

microphone and talk on the currently

selected audio channel(s). Tap again to

disable the microphone.

° Momentary – Press and hold the

button. The microphone will be enabled

immediately and momentary mode will start

if it is held over a ½ second. In this mode, the

microphone is only active for as long as the

button is held down.

• "O" – Tap the button to listen or talk to the

offense audio channel. The light next to it will

activate when selected.

• "X" – Tap the button to listen or talk to the

offense audio channel. The light next to it will

activate when selected.

6. The default for the microphone gain is level four,

which is adequate for most events, however, the

microphone gain can be adjusted up or down if

desired.

• Adjusting the XO-1 Microphone Gain

° Place the headset on.

° Once the beltpack has finished booting, press

and hold both the <O> and the <TALK>

button for 3 seconds. After 3 seconds a voice

prompt will indicate "MIC ADJUST" mode

has been entered.

° As holding the <TALK> button, press the

and hold the <O> button for less gain, hold

the <X> button for more gain.

° There are ten levels of microphone gain.

Each indicated by a voice prompt. Level 4 is

the default.

° Release the “O” or “X” button, and the

<TALK> button when at the desired level.

• The higher the microphone gain the louder that

beltpack user’s voice will sound to other users.

Halftime

1. During halftime leave the XO-AP base station

“On”.

2. The XO-1 beltpacks may be turned off for halftime

to conserve battery life, or left on.

3. If the XO-1 beltpacks are turned off at halftime,

turn the beltpacks on, one at a time. Again, the

beltpack’s battery light will indicate immediately,

but the unit will require up to 20 seconds to

complete start-up.

Before the Next Use

(Charging Instructions)

1. Ensure the XO-1 beltpacks are in the “OFF”

position.

2. Ensure the XO-AP base station is in the “OFF””

position.

XO-1 Beltpack: Plug the XO-1 beltpack charger

into the charge jack on the bottom of the beltpack.

The beltpack should be charged in a room

temperature location. The LED on the bottom of

the unit indicates the charge status.

• RED = Charging

• GREEN = Charging Done

After an event the XO-1 beltpack will need to

charge for at least 6 – 8 hours.

The beltpacks may be left on charge indefinitely.

XO-AP base station: Plug the XO-AP battery

charger into the charge jack on the bottom of the

beltpack. The base station should be charged in a

room temperature location. The LED on the

bottom of the unit indicates the charge status.

• RED = Charging

• GREEN = Charging Done

After an event the XO-AP base station will need to

charge for at least 10 – 14 hours.

The XO-AP may be left on charge indefinitely.

Long Term Storage

“Long term storage” of the system is defined as no

use of the system for 1 month or longer. Due to the

internal Li-Ion batteries of the XO-1 and XO-AP,

care should be taken in long term storage. Use the

following steps to ensure the best performance of

the system after it comes out of storage.

1. After the last event or game of the season:

• If the XO-1 or XO-AP batteries were used for

four hours or less then do not recharge the

internal XO-1 or XO-AP batteries. (Please see

the discussion of “Li-Ion batteries” in the follow

part of this section as to why)

• If the XO-1 or XO-AP batteries were used for

more then four hours then recharge the internal

XO-1 or XO-AP batteries for two hours then

take them off charge (Please see the discussion

of Li-Ion batteries in the follow part of this

section as to why)

2. Store the XO-1's and XO-AP in a clean, cool, dry

location away from heat. The temperature of the

storage location should not rise above room

temperature. The recommended temperature range

of the storage location is 32 - 77° F (0 – 25° C).

3. Every 6 months charge the XO-AP and XO-1 for

three hours then take off charge. Do not fully

charge. This prevents the battery from

over-discharging and helps maintain the battery’s

performance.

5-3

Li-Ion Batteries

The Li-Ion batteries used in the XO-1 and XO-AP are

excellent batteries for portable, outdoor applications.

They have a high energy density (energy per weight)

compare to other rechargeable battery technologies

(NiCd, NiMH, Alkaline, Gel Cells), are low

maintenance, and offer superior performance at low

temperatures.

For best performance after long-term storage, Telex

recommends the batteries be charged to 30% - 50% of

capacity before being placed in storage. This is the

typical battery capacity left after a sporting event, such

as a football game. Li-Ion batteries retain nearly all

their capacity, after long-term storage, if stored in dry,

cool temperatures with only 30% to 50% charge. They

can lose up to 20% capacity if stored for long term

right after being fully charged.

It is also a good idea to charge the XO-AP and XO-1

batteries once every 6 months for three hours then take

off charge. Do not fully charge. This helps to maintain

the battery's performance and prevent any

over-discharging.

Software Version

The software version of the base station and beltpack

may be seen near the top of the screen on the user

configuration menu. To get to this screen follow the

instructions under "Logging into a Beltpack" in

Section 6.

The software version may also be heard via a voice

prompt when the beltpack is booted in programming

mode.

1. Plug a headset into the beltpack.

2. Press and hold down the "X" button on the

beltpack. Keep holding the "X" button and turn on

the beltpack.

3. Hold the button down until the voice prompt

"Wired" followed a second later by the software

version letter is heard.

5-4

Encryption Code

The Legacy system uses a 64 bit DES (Digital

Encryption Standard) encryption algorithm to encrypt

all audio in the system. The beltpacks in the system

have a “key” in the software that the algorithm uses as

the basis for the encryption. The same “key” must be

used in all beltpacks on the system for communication

to occur. The base station only relays the audio, and as

such, does not need any encryption code set. The

beltpack key can be anything from numbers to

sentences to hexadecimal letters. For example the

phrase, “The legacy system works great for our

coaches”, could be the “key” for the encryption. The

only criteria is the phrase/numbers/letters be no more

than 80 characters long (this includes spaces and

punctuation).

This encryption is active on all units from the factory

and does not have to be “turned on” by the user. The

user may want to change their key to something

unique. This may be done by following the steps

below:

Logging into a Beltpack (XO-1)

Please reread the operation and encryption section of this manual

to make sure you have completed system set-up properly. The

following contains troubleshooting tips that may be helpful in

solving the problem.

Section 7 - Troubleshooting

If you are unable to solve the problem, contact the manufacturer

or dealer from whom you purchased the system for assistance.

Problem Possible Cause Solution

RF range of all the beltpacks is less than

normal and/or beltpacks are

experiencing "break-up" of audio in an

area where they have worked well in the

past.

• Antenna is not connected to the

XO-AP.

• The two antenna connections are not

connected to the right connectors on the

XO-AP.

• WiFi RF interference has occurred.

• Non-WiFi RF Interference has

occurred.

• Connect the antenna to the XO-AP.

Make sure the correct cable of the

antenna goes to the corresponding

connector on the XO-AP. The XO-AP

front label indicates the transmit and

receive connectors.

• The XO-AP front label indicates the

transmit and receive connectors. The

antenna's cables are labeled as to their

connection point.

• Find the source of the interference and

shut it down. Sources of WiFi

interference could be: Laptop/Desktop

computer with its wireless card on or

WiFi AP in or near the press box.

• If the interference cannot be found or

shut off then press and hold the

<SELECT> button for 3 seconds (until

the decimal point flashes), then release.

The unit will do a clear scan and place

itself on the clearest channel. The

beltpacks do not have to be turned off,

they will follow the XO-AP to the new

channel within a few seconds after the

clear scan is done.

• Find the source of the interfernce and

shut it down. Sources of interference

could be: Microwave oven in pressbox,

2.4GHz courdless phone nearby, using

a Bluetooth headset near the XO-AP or

beltpack.

• If the interfence cannot be found or shut

off then manually select a different RF

channel by hitting the <SELECT>

button. Make sure the new channel is at

least several channels away from the

old channel for the best chance of

avoiding the RF interference. The

beltpacks do not have to be turned off,

they will follow the XO-AP to the new

channel after a few seconds.

802.11 RF Channels

The Legacy system has the ability to operate on any

one of eleven RF channels. Although there are several

different frequency channel settings, there is overlap

between the channels. There are three

non-overlapping channels available in the FCC

regulatory domain. When choosing frequency

channels for systems in the vicinity of each other, you

should choose frequency channels that do not overlap

(e.g. Channels 1, 6, and 11).
